/* ═══════════════════════════════════════════════════════════════════════════
   SYNC · Panel App Analytics — dark-first, matching the Panel Geography build.

   Two palettes live here, both validated, neither hand-tweakable step by step:

   · categorical (--cat-1…8) — series identity in the trend chart and the
     source split. Validated with the dataviz validator against --surface-1
     (#111b25): lightness band PASS, chroma floor PASS, worst adjacent CVD ΔE
     35.9 deutan / 10.2 tritan, contrast PASS. The tritan figure sits in the
     8–12 floor band, which is legal ONLY alongside a second channel — every
     chart here ships a legend AND direct labels for that reason.
   · sequential (--seq-1…6) — one teal hue, light→dark, for magnitude
     (heatmaps). Monotone OKLCH lightness, ≥0.06 ΔL per step.

   Regenerate a whole ramp if it changes; never nudge one step.
